Hi, I discovered this beautiful piece of software yesterday, but unfortunately I have the same problem.
I'm using a Yeelight Meteorite Celing light which has a primary white light and a secondary ambient RGB light, but the software can only address the white light (as does the Xiami remote control).
Are you by any chance planning to update Jeelight to support newer Xiaomi hardware? A lot of the new models can also switch to "night mode" used to create a low light environment.
Thank you very much for creating this exciting app and let us know if we can help out with hardware-testing or anything.
